1037740-25-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1037740-25-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,7,7,4 and 0 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1037740-25:
(9*1)+(8*0)+(7*3)+(6*7)+(5*7)+(4*4)+(3*0)+(2*2)+(1*5)=132
132 % 10 = 2
So 1037740-25-2 is a valid CAS Registry Number.
